The Cubs selected Pomeranz's contract from Triple-A Iowa on Friday, Bruce Levine of 670TheScore.com reports.
Pomeranz was cut loose by the Angels in mid-June after turning in a 5.01 ERA and 16:12 K:BB across 23.1 innings. The veteran left-hander excelled with the Cubs in 2025, logging a 2.17 ERA and 57:15 K:BB over 49.2 innings, and he'll aim to rediscover that form after making two scoreless appearances for Iowa.
